FIG. 1 illustrates a screen bracket 100 in accordance with an embodiment of the present disclosure.

The screen bracket 100 may be applied to a vehicle-mounted rotating screen 200.

The screen bracket 100 can work with a display screen 300 and a driving device 400, the screen bracket 100 is used to support and fix the display screen 300 and the driving device 400, and the driving device 400 is used to drive the display screen 300 to rotate.

As shown in FIGS. 2 and 3 , the screen bracket 100 includes a rotating base 10, a connecting shaft 20 and a limiting member 30. One end of the connecting shaft 20 is connected to the display screen 300, and another end of the connecting shaft 20 is rotatably connected to the rotating base 10. The limiting member 30 is fixedly disposed in the rotating base 10, and the limiting member 30 is located on one side of the connecting shaft 20.

The driving device 400 is disposed in the rotating base 10, and the driving device 400 is connected to the connecting shaft 20. The driving device 400 is used to drive the connecting shaft 20 to rotate, and the limiting member 30 is used to maintain the connecting shaft 20 at a specified rotation angle.

Referring to FIGS. 1 and 3 , the rotating base 10 may be fixed to the center console of the vehicle, and the driving device 400 drives the connecting shaft 20 to rotate in response to the control of an electrical signal, so as to drive the display screen 300 to rotate to a specified rotating angle, for example, the display screen 300 may rotate to 90° and 180°. When the display screen 300 is rotated to 90°, the display screen 300 is in a vertical screen mode. When the display screen 300 is rotated to 180°, the display screen 300 is in a horizontal screen mode. When the rotation of the display screen 300 is complete, the limiting member 30 may position the display screen 300 at the current rotation angle.

Referring to FIGS. 3 and 4 , an end of the connecting shaft 20 proximate to the rotating seat rotating base 10 may define a plurality of locating holes 21, the plurality of the locating holes 21 are spaced apart around a circumference of the connecting shaft 20, and the locating hole 21 runs radially through the connecting shaft 20 along the rotation direction of the connecting shaft 20. When the connecting shaft 20 is rotated, the plurality of the locating holes 21 are moved in a circular motion at the same time.

The limiting member 30 includes a telescopic rod 31, the telescopic rod 31 has an extended state and a retracted state, and the limiting member 30 can change the telescopic state of the telescopic rod 31 under the control of an electric signal. The telescopic rod 31 is disposed toward the connecting shaft 20, and the telescopic direction of the telescopic rod 31 corresponds to the rotation radial direction of the connecting shaft 20.

When the telescopic rod 31 is switched from the retracted state to the extended state, the telescopic rod 31 as a whole moves in a direction close to the connecting shaft 20. When the telescopic rod 31 is switched from the extended state to the retracted state, the telescopic rod 31 as a whole moves in a direction away from the connecting shaft 20.

The telescopic rod 31 is provided corresponding to the plurality of the locating holes 21, and the internal shape of the locating hole 21 matches the shape of the end of the telescopic rod 31. The plurality of the locating holes 21 correspond to different rotation angles, and when the connecting shaft 20 is rotated to a specified rotation angle, the locating hole 21 corresponding to that rotation angle are facing the telescopic rod 31.

In the embodiment, the number of the locating holes 21 is 2, and the connecting shaft 20 can be rotated at angles of 90° and 180°. When the connecting shaft 20 is rotated to 90°, one locating hole 21 is facing the telescopic rod 31, and when the connecting shaft 20 is rotated to 180°, another locating hole 21 is facing the telescopic rod 31. The number of the locating holes 21 and the rotatable angle of the connecting shaft 20 can be set according to product requirements and can be adjusted in practical applications.

In the embodiment, when the telescopic rod 31 is in the extended state, the telescopic rod 31 may extend into the opposite locating hole 21 and clamp into the corresponding locating hole 21, and the limiting member 30 prevents the connecting shaft 20 from rotating. When the telescopic rod 31 is in the retracted state, the telescopic rod 31 can extend out of the opposite locating hole 21 and detach from the corresponding locating hole 21, and the limiting member 30 does not interfere with the rotation of the connecting shaft 20.

Referring to FIGS. 1 and 3 , in the embodiment, the process by which the rotation of the display screen 300 occurs is as follows:

Firstly, the telescopic rod 31 is made in the retracted state.

With the telescopic rod 31 in the retracted state, the driving device 400 rotates the connecting shaft 20 to a specified angle of rotation, for example, the display screen 300 rotates to 90° or 180°.

After the rotation of the connecting shaft 20 is completed, the telescopic rod 31 is switched to the extended state, and the rod telescopic rod 31 is clamped to the corresponding locating hole 21.

When the display screen 300 needs to rotate, the telescopic rod 31 can be far away from the locating hole 21. When the display screen 300 does not need to rotate, the telescopic rod 31 can be clamped and matched with the corresponding locating hole 21 to limit the rotation angle of the connecting shaft 20, thereby preventing the display screen 300 from rotating under external forces (such as when the user manually rotates the display screen 300 due to improper use), this can reduce the risk of damage to the driving device 400 or related connection structures and improve durability.
